US 2006/0040159 A1 · Fuel cell stack

Abstract

A terminal plate, an insulating plate, and an end plate are stacked on a stack body. The terminal plate has current collectors at least at lower portions of an oxygen-containing gas supply passage, a coolant supply passage, a fuel gas discharge passage, a fuel gas supply passage, a coolant discharge passage, and an oxygen-containing gas discharge passage. The current collectors contact the water generated in the reaction or a coolant for collecting electricity.

Dependent claims

A fuel cell stack comprising electrolyte electrode assemblies and separators stacked alternately in a stacking direction, said electrolyte electrode assemblies each including a pair of electrodes, and an electrolyte interposed between said electrodes, wherein

fluid passages extend through said fuel cell stack in the stacking direction such that fluids including at least one of a coolant and reactant gases flows through said fluid passages;
and
a current collector is provided at least at one of said fluid passages, and said current collector contacts said fluid flowing through said fluid passage for collecting electricity.

Dependencies are inferred from the claim text.
